Lotide

A mini clone of the Lodash library.

Purpose

BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @emilywaters/lotide

Require it:

const _ = require('@emilywaters/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• assertArraysEqual(...): Compares arrays and logs the results as pass/fail
• assertEqual(...): Strict comparison of primitives
• assertObjectsEqual(...): Compares objects and logs the result as pass/fail
• countLetters(...): Counts the occurence of letters in a string, and stores the letters with their occurences as key/value pairs
• countOnly(...): countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• eqArrays(...): compares two arrays for strict equality
• eqObjects(...): compares two objects for strict equality
• findKey(...): finds a specified key in an object
• findKeyByValue(...): find key(s) that have a specified value
• flatten(...): Flattens nested arrays into a single array
• head(...): Grabs the element of an array at index position 0
• letterPositions(...): Maps each letter to a key and stores its index position(s) in an array from a given string
• map(...): maps an array into a new array
• middle(...): Grabs the middle element of an array, in the case of even length arrays, grabs the middle two elements
• tail(...): returns an array that is from index position 1 and onwards
• takeUntil(...): Takes elements of an array up to a position specified by an element value
• without(...): return a subset of a given array, removing unwanted elements
